1. Introduction. Ball mill is one of the most commonly used mills for the crushing and grinding of mineral ore. It is generally used to grind material down to the particle size of 20 to 75 μm and can vary in size from a small batch mill up to a mill with outputs of hundreds of tonnes per hour.

Webmass balance wet ball mill mill - daconline.in. 2016 01 26 losses as well as mass transfer Finally, In the ball mill case, the energy balance found in equation 2 is sufficient as all the ore and water components of the slurry at the feed and discharge are at a similar . …

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

4. 1. The mass and energy going into the box must balance with the mass and energy coming out. The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored . Raw Materials = Products + Wastes + Stored Materials. ΣmR = ΣmP + Σ mW + ΣmS (where Σ (sigma) denotes the sum of all …
